Update Your System Before you begin, make sure your Raspberry Pi is running the latest version of the operating system (Raspbian) by opening a terminal and typing:
```
sudo apt-get update && sudo apt-get upgrade
```
Install Required Packages Next, install the necessary packages for WiFi configuration by running this command in the terminal:
```
sudo apt-get install -y wpasupplicant
```
Find Your Network SSID To connect to a WiFi network, you’ll need to know its Service Set Identifier (SSID). This is typically the name of your home or office network that appears on your device when searching for available networks. You can find this by opening the WiFi settings on your computer or mobile device and noting the network name.
Configure Your Raspberry Pi Now it’s time to configure your Raspberry Pi to connect to the WiFi network. Open the WiFi configuration file using a text editor (e.g., nano):
```
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
```
Add the following lines at the end of the file, replacing <SSID> with your network’s SSID and <PASSWORD> with your WiFi password:
```
network={
    ssid="<SSID>"
    psk="<PASSWORD>"
    key_mgmt=WPA-PSK
}
```
Save the changes by pressing Ctrl + X, then Y, and finally Enter.
Restart the WiFi Service To apply the new settings, restart the WiFi service using:
```
sudo systemctl restart wpa_supplicant
```
Verify Connection To check if your Raspberry Pi is connected to the WiFi network, run:
```
iwconfig
```
Look for ESSID: followed by your SSID in the output. If it’s there, you’re all set! You can now access your Raspberry Pi remotely or transfer data wirelessly.

That’s it! Your Raspberry Pi is now connected to WiFi. With this setup, you can easily access and control your device from anywhere with an internet connection, making it a valuable tool for remote monitoring, automation, and more.
